Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
ground beef or ground turkey
olive oil
onion, chopped
garlic, minced
low carb marinara sauce
bell pepper, diced
mushrooms, sliced
italian seasoning
salt
black pepper
mozzarella cheese, shredded
parmesan cheese, grated
pepperoni slices
Directions
I start by preheating the oven to 375°F (190°C) and lightly greasing a casserole dish.
In a large skillet, I heat olive oil over medium heat. I add the chopped onion and cook it until it softens. Then I stir in the garlic and cook it briefly until fragrant.
Next, I add the ground beef or ground turkey and cook it until it is fully browned, breaking it apart as it cooks. Once the meat is cooked, I drain any excess grease if necessary.
I stir in the diced bell pepper, sliced mushrooms, marinara sauce, Italian seasoning, salt, and black pepper. I let the mixture simmer for a few minutes so the flavors combine.
I transfer the mixture into the prepared casserole dish and spread it evenly. Then I sprinkle the shredded mozzarella and grated parmesan cheese over the top.
I arrange the pepperoni slices on top of the cheese and place the casserole in the oven.
I bake the casserole until the cheese is melted, bubbly, and lightly golden on top.
After baking, I allow the casserole to cool for a few minutes before serving.

Servings: 4 servings
Preparation time: 10 minutes
Cooking time: 25–30 minutes
Total time: about 35–40 minutes
Variations
I sometimes replace the ground beef with ground chicken or sausage for a slightly different flavor. Another variation I enjoy is adding chopped spinach or zucchini to include more vegetables.
When I want a spicier version, I add crushed red pepper flakes or sliced jalapeños. I also occasionally mix cream cheese into the sauce mixture to create a richer and creamier casserole.
storage/reheating
I store leftover pizza casserole in an airtight container in the refrigerator for up to four days.
When reheating, I place a portion in the microwave for a few minutes or warm it in the oven at a low temperature until heated through. This helps the cheese melt again and restores the casserole’s texture.
